When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

The central pattern generator (CPG) networks that generate relatively simple motor outputs are ideal experimental models for circuit analysis. Locomotor CPGs in the ventral spinal cord function ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
